Paper Abstract

A new processing of spectra for pattern recognition was created in order to detect explosives. Partial Least Squares (PLS) was used to create vector for recognition and those were using for discriminant analysis. PLS was adjusted with a discriminant function. IR spectra of TATP, DNT and TNT traces in air were recorded. Spectra of free air of those explosives were measured. NIR and MIR regions were studied and were used for PLS vector. NIR region is statistically significant. Two PLS were necessary for good discrimination for those explosives.
